Performing a "browse subject" search for "subject headings" in the Library of Congress catalog might be helpful also. There are a number of subdivisions listed.
Good luck!

Hi Joseph,

   I'm sure there are hundreds (perhaps thousands) of such controlled vocabularies!  But here is a website that might give you a starting point:

Subject: [eduCAT] How many controlled vocabularies?

Friends and colleagues,

I am wondering if anyone knows how many controlled vocabularies exist in the world today?  I am aware of the OBO Foundry, Taxobank, and I have started to collect lists from other places, but I don't have a clue as to whether these are a representative sample or not.  I can only start to understand if I know how many are out there (in every different version).  Does anyone have an idea?  Does anyone know where I might look?  Does the SAS collection at Toronto serve as a complete inventory of these things?

And by controlled vocabulary I mean classification schemes, thesauri, terminologies, ontologies, etc.  Anything that is a restricted set of semantics used in the process of indexing or labeling.  Yes, that is very general ;-)

Thanks for any and all help you can provide.

Sincerely,
joe
